Unused item. I bought it but I don't have a chance to use it, so I'm putting it up for sale! Although it hasn't been used, I opened it to take pictures. It is unused, but since time has passed, I will list it as a used item. To prevent any swapping, returns after purchase will not be accepted. Thank you for your understanding and purchase!
